Abstract: We give a new method of computing tau functions for a wide class of integrable systems. We illustrate this method in the case of Drinfeld—Sokolov hierarchy. As an application, the FJRW invariants in full genera associated with a simple singularity are reduced to the topological ODE. The talk is based on a series of joint works with Marco Bertola and Boris Dubrovin.
